A man accused of bludgeoning his girlfriend to death, then staging a car accident to cover it up, confessed repeatedly and in elaborate detail to his wife, Denver jurors heard Tuesday in the murder trial of Robert Walters.

Elena Walters, 25, surreptitiously recorded more than a dozen sometimes graphic, sometimes barely intelligible conversations in the months after the alleged crime.

On some tapes, Robert Walters, 25, acknowledges killing Britney Brashers in 2009 and threatens to kill his wife because she knows too much.

In one recording, Robert Wal ters threatens suicide, saying he always believed he would never hit a woman.

“Then I kill a girl by hitting her, and I can’t fix it. . . . There’s no way to fix it. There’s no way to fix it,” he says on tape. “Just die — that’s the only honorable thing to do.”

During the trial in Denver District Court, defense attorneys repeatedly objected to the tapes’ being admitted into evidence. They have not yet cross-examined Elena Walters, who is now divorced.

She recounted a tumultuous love triangle that developed when her ex-husband and Brashers were stationed in Iraq with the Air Force.

Elena Walters testified that her ex told her he decided to kill Brashers on Nov. 16, 2009, as he sat in the back of a Denver strip club. She had reveled in the attention she got from a photographer after removing her top during a photo shoot.

On the drive home, he said, he punched Brashers repeatedly, kneed her in the face, tried to choke her and tried to snap her neck before placing her in the driver’s seat and staging a wreck.

“I heard the same story every single day for a couple of weeks,” Elena Walters said.

She said her former husband described Brashers as a “horrible person” who didn’t “need to live.”

Robert Walters told investigators in 2009 that he and Brashers drank heavily that night and that he fell asleep in the car just before she crashed.

Prosecutors said in one set of recordings, made nearly two months later, Robert Walters recounted in a monotone detail how he killed Brashers. The recording was barely intelligible in the courtroom, though at one point onlookers could hear a high-pitched “ahhh” as Walters imitated his alleged victim.

” ‘Ahhh,’ ” Walters says on the tape. “She tried to scream. ‘Ahhh.’ “

In another recording, Walters hurled abuse at his wife, calling her ignorant and swearing profusely before threatening to kill her.

“I’ll make it my goal. It’ll be the last thing I’ll ever do is hunt you down and (mess) you up,” Robert Walters tells Elena Walters. “Anyone who stands in my way will die.”

Elena Walters said her ex-husband and Brashers had a history of physical fights. About a month before Brashers’ death, the pair got into a brawl in Colorado Springs.

Robert Walters landed in an El Paso County jail and launched a brief campaign to get Brashers kicked out of the Air Force before the pair reunited, Elena Walters said.

“I’m going to destroy her,” Robert Walters told his then-wife in a recorded jailhouse phone call. “We need to (expletive) this girl over.”

While state education officials are sharing their proposals aimed at ending the teacher shortage in Colorado, the state’s largest teacher association says the overall plan lacks specifics and shortchanges traditional preparation programs.
